Patented April 23, 1907-.

- Be it known that I, JOHN W. VAUGHN, a citizen of the United States, "and a resident of Noroton Hei hts,-in the county of Fairfield and State of onnecticut, have invented certain new and useful Improvements in Vending-Machines, of which the following is a specification. A

This invention relates to new and-useful. improvements in vending machines and particularly to such machines from which the urchased articles are to be delivered in a oose condition and warmed or heated, for. example, such as pop-com or peanuts.

The object of my invention is to rovide a new and improved machine of t 's class,

get out of order, is economical, permits of selecting one kind of article for delivering from several, heats the article delivered, automatically turns on the heating device upon the insertion of a coin, automatically turns its functions and which machine also delivers a piece of paper and deposits the goods delivered upon this paper.

Figure 1 1s a vertical longitudinal sectional view through one construction of my improved vending machine which illustrates) my invention. Fig. 2 is a front elevation of. the samewith parts broken out to .show the interior mechanism. Fig. 3 is a horizontal 4, and 6' representdetails.

l The entire mechanism is contained within a suitable casing -1,v preferably having a peaked roof for t 1e purpose of shedding the a diskprovided with a coin slot 3 communieating with a vertical coin chute 4 which chute is provided at its lower end with a lateral arm 5 open at the bottom. Beneath the ment 6 having a rounded upper edge upon which the dropping coins can strike and re-- bound into the'lateral arm 5 of the chute. Lead coins will not" rebound and will drop through the open bottom part 7 of the arm adjacent to the abutment 6 and drop into the bottom .of the casing 1'. A shaft 8 is mounted centrally in the disk 2 and is rovided at its outer end with a crank han le 9' which can be brought against one of two the disk 2 which stops 10 and 11 may be crank handle toward marked with the names of the articles to be I delivered for example, one for pop-com and the other for eanuts. Atwo armed lever'is secured on he shaft 8 directly behind the front of the casin so that by moving said the stop 10 or 11 this two armed lever will also be moved, its two ends movin in opposite directions. With the upper on of the upper arm 12 of this lever a horizontal 'rod 13 is pivotally connected and is provided with two spurs 14 each of which engages a groove 15 in a sleeve 16 mounted to turn axially on a horizontal shaft 17, each sleeve carrying a mutilated pinion 18 and adjacent thereto a crown wheel 19 which crown wheels areon opposite sides of a vertieall movable bar 20 having a'handle 21 projecting through a vertical slot 22 in the front of the machine casing.

As will be'seen from Fig. 2, when the upper end of the arm 12 is moved to the right, the right hand crown wheel 19- will be disen aged from a rack on the right hand side e e of the bar 20 and at the same time the left and crown wheel 19 will be engaged with a rack on the left hand side of the bar 20 and when the upper end of the arm 12 is moved to the left, the left hand crown wheel 19 is disenga ed from its side rack on the bar20 and the rig t hand'crown wheel 19 is engaged with its side rack on the bar 20.

Each mutilated pinion 18 is embraced by the two prongs of a fork 23 mounted to move horizontally and suitably guided, the inner ed es of the prongs of these forks being provided with cog teeth which can engage the teeth of the mutilated pinions 18, as shown in Fig. 1 and it thus follows that when the mutilated inion is turned in the direction from left to right, and engages the teeth on the upr prong. of the fork 23, this fork is moved om left to right a predetermined distance, I

whereupon the fork remains at rest and when the crown wheel is turned in the direction from right to left, the teeth of the mutilated pinion move the fork from right to'left and so on. Each fork 23, of which there is one on each side of the machine, is connected by a rod 24 with a slide valve 25 beneath a hopper 26 containing p0 -corn or peanuts .or any other article to e delivered. This slide valve 25 has an opening 27 which can register with the bottom opening of the hopper 26 and also with an opening 28 in the top of a casing 29, it being understood however that the same time.

As shown in Fig.- 1' when the opening 27 of i and the other set for the 35 is' forced through the corres the coin pocket.

said 0 ning 27 the valve does not register with t e 0 ening 28-in the top of the casing 29 and 'yirit the bottom of the hopper 26 at the the slide valve re ters with the bottom of the hopper a re etermined quantity of corn or peanuts t at is as much as the opening 27 will hol can ass into said opening and then when the for 23, its rod 24 and the valve 25 are moved to the right, Fig.. 1, this quantity of material within the ning 27 of the valve is also moved from leit to right until the opening 27 registers with the opening 28 in the top of the casin 29, whereupon the material drops from sai, valve 25 upon the bottom: of the receptacle 29, formed by a pivoted pan 30 upon which the corn or peanuts are to be heated as will be set forth later on. At a later time the fork 23 and with it the rod 27 and valve 25 are moved to the left, the

. valve 25 is again brought beneath the hopperv in positionto receive'a fresh charge of materia and so on. This hop r, va ve and 'receptacle 29 and -pan130, an fork 23am found on-eachside of the machine, one set for the nuts. eneath the open bottom of the ateral arm 59f the coin chute 4 is located aco pocket 3 '31 open at the top andbottom and in its nor- 'mal osition above a coin rest 32 in line with the ottoni of the coin pocket 31. This pocket is provided with an opening 33in each side into which openin s rongs 34 extend from the ends of aforied lever 35 secured-on one end of a bell crank lever 36. pivoted to swinghorizontall at 37. The other arm of this lever 36 is for ed as at 38 and between the prongs of this fork the lower end of the arm 39 extends, which arm 39 forms the lower part of the lever connected with the shaft 8 ca 'ng the crank handle 9. As the crank han d l e is turned in one direction or the other, the lever 36 is moved horizontally on its pivot 37 and thereby. one or the other of the prongs 34 on the ends of the forked lever ending opening' 33 into the coin pocket an when there is a-coin in the pocket thisprong encounters the said coin an by pushing on the coin shifts This coin ,ocket is attached to one end of a bell cranl lever 40'pivoted at 41 and provided at its with a fork 42 embracing a pin 43, projecting from a bar 44 guided to move horizontally and which is ivotally connected at its center, as at 45, with adownwardly projecting arm of a lever 46 pivotedat 47 and terminating at I its top in the-two arms or prongs 48, the uper end of each being shaped like a crutch or ork and enteringa groove 49 of a sleeve 50 mounted to slide and to turn loosely on afixed horizontal shaft 51 there being one such sleeve 50 at each side of the vertically movable bar ,20 previously mentioned. Adjaopposite end cent to each sleeve 50 is a large cog wheel 52 and a crown wheel 53, the teeth of which crown wheels can engage the said side racks.

on the vertically movable bar 20 which have been previous] mentioned, so that as said bar 20 moves own the crown wheels 53 and the cog wheels 52 are rotated. The wheel 52 carry spring pawls 53 for rotating these wheels 52 m one direction onl that is when the bar 20 is forced down as s own-in .Fig. 4; It is clear that when the lever 46 is swungin one direction'by the bar 44 that one crown wheel will be engagedwith its corresponding side rack of the vertically movable bar 20 and the other crown wheel 53 willbe disengaged so that by t the crank handle 9 -to.either the sto 10 an 11 one crown wheel 19 on the fixed s aft 17 and onefc'rown wheel 53 on the. fixed shaft 51 will be engaged with its corres nding side rack on the vertically movable 821-20 and the two crown wheels on the other side willbe aged. I 1 Each cog wheel 52 is engaged witha wheel 54 o a spring motor 55 of conventions construction and the details of which 'need not be described, and which motor has an escapement 56 of any conventional construction. 4

Each motor operates a wheel 57 having laterally projecting pins 58 which can strike on a tappet on the lower end of a lever 60 pivoted at 61, which lever is provided at its upper end with a hammer head 62 which can strike against the bottom of a pan 30. when the latter is .in horizontal position. Therefore when'the spring motor is wound and rmitted to'operate it causes this striker or.

, ammer 62. to strike the bottomof the pan and thereby agitate and throw about the pop corneor peanuts u on this-pan. At each side of the bar 20 a ever 63 is pivoted at 64 in such a manner that the free end of upon the to of the'vertically movable bar 20 andthis ever 63 is connected by a pivoted link 64, with a link 65 pivoted at 66' which link 65 .in turn is connected by a link 67 with a pivoted pan 30; When the bar 20 is -in the raised throws the pan 30 into air inclined position, but when .the bar .20 is .forced down, the weight of the pivoted lever 63 acting by means of the several pivoted links on the a pan 30 swings this pan into horizontal position beneath the receptacle 29 as shown in dotted lines and the pan-is held in this position until the bar 20again rises and brings position as shown in 1 it' this lever, when in horizontal position,rests IIO the] ver 63 into horizontal (position. A fine coile sprin 68 slightly wi er thanthe'slot 22 is secure above the top of the bar 20 and passing over a ide pulle 69 is attached to the handle 21 that as the bar 20 is forced down by means of the handle 21 this coiled spri 'is uncoiled and pulled down behind the :fit so as to lrectly be d the slot 22 so sauna implements that would dam e the ma- "chmery, and as the bar rises t is spring 68 automatically coils. Aslide 22 connected with the handle 21 covers the slot '22 bene'ath the handle. The bar 20 is provided at its front Wlth a rack 70 and with a notch 71 at the top of the rack and a notch '72 at the bottom of this. rack. .A triangular pawl 73 is pivoted to an arm,74 in such a position that when the bar 20'is raised this triangplar pawl rests in'the notch 72, and as the ar 20 is forced down this pawl is so turned that one side edge will be at the side of the rack 70 and will notinterfere with the forcing down of theibar 20 but if the bar 20 is released this bolt instantly' catches and prevents upward movement of the bar 20. Whenthe bar 20 has been forced down as far as possible the notch 71 arrives at the pawl 73 and turns the same in such a position as not to interfere with the u ward movement of the bar '20 but now ment of the bar 20 and vice versa, it thus alternately prevents upward and downward I movement of the bar. Springs 75 connected with the casing and with the top of the bar 20 pull the latter upward when released and a piston on the lower end of the bar 20 and fitting in a cylinder 77, provided with a release valve 78 prevents the springs 75 from ulling the bar 20 upward too suddenly. he bar 20 is provided with a shoulder 79; which can be engaged b the-lower end of a locking lever 80 pivote at 81 (Fig. 5) and the upper end of this locking lever is in the ath o a stud or lug 82 fiI'OJBOtiIlg laterally om the corresponding w eel 52. Of course it is to be understood that there are two of these ivoted bars 80 both of which can en age t e shoulder 79 of the bar 20. As the ar 20 is forced down the wheel 52 is turned 1 in the direction from left to ri ht by the mechanism described and the rod 80 swin s 'over the shoulder 79. As the spring of t e clock motor unwinds the corresponding wheel 52 is turned in the direction from right to left and'by the time that the spring has been unwound, the lug 82 strikes the lever and throws it off the shoulder 79 thus permitting'the bar 20 to. be moved uppurpose that will appear wheel 86 on'a shaft 86 carrying a mutilated pinion 87 which can engage the toothed shanks of a horizontally guided fork 88 which is connected with a horizontal slldlllllfi valve 89 of an acetylene gas generator ta 90 having a hopper 91. As the shaft 20 is forced down the valve 89 is moved from the position shown in Fig. 1' to the left so as to dro a charge of carbide into the generator 90 as the mutilated pinion continues to rotate the valve 89 is movedback'into the position shown fora fresh chargeof carbide. The acetylene enerated is conducted into a' gasometer 91 0 any improved construction and which has a release valve 92 from which the gas can pass through'a flexible tube 93 "to the outer air when the pressure is-too high.

A pipe 94 extends from the acetylene generator90 to a gas burner .95 beneath the an 30 and this burner has its cock connected by a. link 96 with the pan 30 in such a'manner that when the pan'is in horizontal position, the as is turned on and when the pan is tilter the gas is almost entirely turned off but not comp etely so as to leave what is commonly known as a pilot flame. An elbow lever 97 is pivoted at 98 to the one side of the front of the machine and is connected by a slot and pin with the horizontally moving rod 44 and is also acted upon by springs 99. When the bar 20 rises a pin 100 on the same strikes a horizontal arm of the lever 97 which causes the lever 36 to swing back into normal position and also brings the coin pocket 31 ack into its normal position for receiving the next coin. e

A roll of paper 101 shown in dotted lines in Fig. 1 and in full lines in Fig. 3, is suitably mounted in the machine andthe paper asses between two feed rolls 102 directly be rind a horizontal shelf 103% the lower end of an inclined chute 104 down which the contents is guided when it slides off a tilted pan.

The lower paper feed roller 102 is fixed on a shaft 105 car ing a ratchet wheel 106 which is rotated fi' om a pinion 107 engaging the rack 83 so that when the bar 20 is forced down this lower feed roller 102 is turned in the direction from left to right and feeds a length of paper m upon the shelf 103. When the bar 20 rises the awl on' the cog wheel 107 slides over the rate et wheel 106 without operating it. i f

A knife 110, pivoted at 112 is normally. held raised by a spring 111 and when the bar 20 rises a toe 113 strikes this knife and iwings it downward to cut off the paper, see

The operation is as follows :-The purchaser deposits his coinwhich drops into the ocket 31, if it is a perfect coin and if it is a lzsad slug it drops to the bottom of the box, whereupon the purchaser moves the crank on the front of the machine over to the stop according to the selection that he has made. Thereby the crown wheels 19 and 53 on one side or the other of the machine are thrown into operative osition with the bar 20. The bar 20 is then orced down whereby a corresponding plan 30 is brought into horizontal position, t e corresponding feed valve 25 for the material to be delivered is brought into proper position to drop the material upon the FIO 45 '5. In a vending machine, the combination pan, the clockwork is started, the gas is with a heating evice ofa pan'above the nately in op .on the pan-is a timid by the blows of the hammer-62.

'tially as set forth.

-with a hopper, of means for discharging a .rial after it has been heated, substantially as turned on, the pan is heated andthe material en the bar 20 arrives in its lowest position it is locked in lace by one of suflicient for the flame to heat the pan and the contents thereon, whereupon the lug 82 on the corresponding wheel 52 strikes the corresponding lever 80 which releases the bar 20 and it is slowly pulled up by its springs and so on. The pan it tilted, the as turned off and the contents of the pan shde down the chute 104 upon the paper m on the shelf'103- and the atper is cut off.
